Abstract

Disclosed is a vertical focusing circuitry for a high resolution monochrome display monitor. Recently the high resolution display monitor, which uses a cathode ray tube, full square (FS) and wide angle deflection, requires dynamic voltage focusing correction. This circuitry can easily generate a dynamic focusing signal of parabolic waveform.
